Comment on It's interesting that we have multiple appliances in the kitchen who's sole job is to turn electricity into heat.

  For heat pumps, the thing they’re moving is heat.

    They’re really moving refrigerant. It’s just that the refrigerant keeps changing temperature (heating up at one end of the journey and cooling down at the other end).

      More specifically, we force it to undergo phase changes under different pressures, and in doing so it absorbs/releases latent heat in the air. It’s converting latent heat to sensible heat.

  And what is that movent? Eventually decays into heat.

    I understand that, and called it out in my comment. Heat being a byproduct of movement does not mean that a device that creates movement “only” creates heat. That’s like saying all drink dispensers only dispense piss, because what does it eventually turn in to?
